string - integer length in javascript -


stoopid question time!

i know in javascript have convert integer string:

var num = 1024; len = num.tostring().length; console.log(len);

my question this: why there no length property integers in javascript? isn't used often?

well, don't think providing length properties number helpful. point length of strings not change changing representation.

for example can have string similar this:

var b = "sometext";

and length property not change unless change string itself.

but not case numbers.

the same number can have these 2 representations:

 var = 23e-1; ,   var b = 2.3;

so these 2 representation clear same number can have multiple representation , so, if have length property numbers have change representation of numb.er

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
